SEDIMENT CHARACTERIZATION REPORT

TERMINAL 4, BERTHS 401 AND 410

11040 N. LOMBARD STREET, PORTLAND, OREGON

1.0 INTRODUCTION

The Port of Portland (Port) proposes to conduct a maintenance dredging event

at Berths 401 and 410 at Terminal 4 along the Willamette River in Portland,

Oregon (Figure 1). To provide chemical quality data on sediment to be dredged

and the future “leave surface” or new surface material (NSM), sediment

characterization activities were completed in accordance with the Sediment

Evaluation Framework (SEF) for the Pacific Northwest (U.S. Army Corps of

Engineers [Corps] et al., 2009) and our Sampling and Analysis Plan (SAP) (Hart

Crowser, 2012). This report presents the results and findings of these activities.

1.1 Terminal 4 and Berth Descriptions

Terminal 4 is located at 11040 N. Lombard Street in Portland, Oregon, on the

east bank of the Willamette River between River Miles 4 and 5.5. Berth 401,

located downstream of Slip 1, was previously used by a grain handling facility

(Cargill, Inc.) until 2004. Currently, the berth is occasionally used as a lay berth.

Berths 410 and 411 are located within Slip 3 and used by Kinder Morgan for

loading soda ash (sodium carbonate) for export. Berths 414, 415, and 416 at

Terminal 4 are located further upstream. The proposed project includes only

Berths 401 and 410.

Figure 2 shows Berth 401 and its bathymetry based on a July 2011 survey

conducted by the Port. The berthing area ranges from 1,127 to 1,427 feet long

and is 150 feet wide. The river bottom within the berthing area varies from

approximately -35 to -57 feet, relative to the Columbia River Datum (CRD). The

design depth of Berth 401 is -41 feet CRD, with 2 feet of overdredge allowance.

The proposed maximum permitted depth is -44 feet CRD.

The bathymetry for Berth 410, as well as the rest of Slip 3, is shown on Figure 3.

The berthing area for Berth 410 is generally the western portion of the north side

of Slip 3 and extends 200 to 300 feet from the berthing wall. Currently, the river

bottom within the berthing area varies from -36 to -61 feet CRD based on the Port

survey in 2011. The design depth of Berth 410 is -41 feet CRD, with 2 feet of

overdredge allowance. The proposed maximum permitted depth is -44 feet CRD.


1.2 Previous Sediment Characterization Activities

Previous sediment characterization and berth maintenance events for Berths 401

and 410 are discussed in the SAP (Hart Crowser, 2012). Berth 401 was last

dredged in 1988. Berth 410 undergoes routine maintenance dredging, with the

last dredging event occurring in 2008 as part of a removal action conducted in

and near Slip 3 (Anchor 2009).

Previous sampling data from Berth 401 have detected mercury, zinc, tributyltin

(TBT), bis(2-ethylhexyl)phthalate (BEHP), DDT, and polychlorinated biphenyls

(PCBs) above SEF screening levels (SLs). Upon evaluation, the SAP identified

TBT and BEHP as the primary chemicals of concern (COCs) at Berth 401. TBT

was detected above SLs only in subsurface sediments and is likely localized near

the middle of the berth. BEHP was also present in the dredge prism sediments.

The other compounds (metals, DDT, and total PCBs) were detected infrequently

above SLs. Based on the COC exceedances and berth use, a “moderate” to

“high” rank was proposed for Berth 401 in accordance with Table 4-2 of the SEF

(Corps, et al. 2009). The Portland Sediment Evaluation Team (PSET) indicated

that a “high” ranking was appropriate PSET (2012).

For Berth 410, previous sediment characterization studies detected relatively high

concentrations of polycyclic aromatic hydrocarbon (PAHs). Other contaminants

include metals (cadmium, lead, silver, and zinc), BEHP, DDx (DDT and its

breakdown products DDD and DDE), and PCBs. Chemical data from two cores

performed in 2007 detected zinc, high molecular weight PAHs (HPAHs), and

total PCBs above SLs near the middle of Berth 410 (Anchor, 2008). These

compounds are COCs for Berth 410. Sediment quality at Berth 410 toward the

mouth of Slip 3 was below SEF SLs. Based on the previous presence of COCs,

we assigned a “high” rank to the berth in accordance with Table 4-2 of the SEF.

PSET (2012) concurred with this ranking.

1.3 Project Description

Maintenance dredging is needed due to the gradual and persistent deposition of

river sediment in the berthing areas that compromise the authorized navigational

depth clearances required for ships. Dredging is imperative for Berth 410 as it is

currently used. Berth 401 is used only occasionally as a lay berth; however, the

Port anticipates putting this berth back in active use soon. The Port will be

submitting a Joint Permit Application (JPA) to the Corps and Oregon Department

of State Lands to obtain the necessary permits to perform maintenance dredging

of these berths.


In-water dredging activities will be performed during the Willamette River in-water

work window from July 1 to October 31. Figures 2 and 3 show the sediment

areas requiring dredging for Berths 401 and 410, respectively. Dredging would be

conducted to -41 feet CRD with a permitted 2 feet of overdredge for advanced

maintenance and inherent dredging accuracy (i.e., to -43 feet CRD). The NSM,

which is equivalent to the pay depth (i.e., the depth to which the dredging

contractor is paid for material removed), is anticipated to average -42 feet CRD.

As such, the estimated maximum dredging volumes for Berths 401 and 410 are

20,000 and 15,000 cubic yards, respectively. While the maximum depth of

dredging is anticipated to be -43 feet CRD, the Port will be requesting a proposed

maximum permitted depth of -44 feet CRD to account for occasional smaller areas

that may exceed the maximum dredging depth of -43 feet CRD.

The Port will use its standard berth dredging methods, which are designed and

have been previously demonstrated to minimize water quality impacts. A

clamshell dredge will remove sediments using a close-lipped bucket operated

either from the dock or from a floating crane. The depth and position of the

bucket and dredge would be monitored by visual and positioning computer

systems, including a global positioning system (GPS). The dredge material will be

placed in a barge and transported for placement at an upland placement facility

(West Hayden Island Placement Facility or Suttle Road Rehandling Facility), or

another approved beneficial use site. For material that is unsuitable for these

placement options, the material will be transported for disposal at a solid waste

(RCRA Subtitle D) landfill. During dredge material handling, transport, or

placement, it is not anticipated that return water flows to the Willamette or

Columbia Rivers will be generated.

2.0 SEDIMENT CHARACTERIZATION OBJECTIVES

The overall objective of this sediment characterization study was to characterize

the quality of the proposed dredge material and NSM. Specific objectives of the

study were to:

Characterize sediment affected by proposed dredging activities along the

berths (i.e., the dredge prisms) to document the quality of the sediments;

Additionally, characterize the underlying NSMs (a.k.a. leave surfaces) along

the berths to document the chemical quality of these remaining sediments;

Collect, handle, and analyze samples representative of the dredge prisms and

NSM sediments in accordance with the SEF;

Compare the sediment analytical results to applicable SLs to evaluate the

nature of the dredge prisms and NSM sediments; and


Evaluate and report the results of the analytical sediment testing in a complete

and timely manner to support the necessary maintenance dredging activities.

Sediment characterization activities were conducted in accordance with our SAP

(Hart Crowser, 2012), comments from PSET (PSET, 2012), the SEF, and an EPA

technical manual for sediment sampling (EPA, 2001). Quality assurance/quality

control (QA/QC) procedures described in our Quality Assurance Project Plan in

the SAP were followed.

3.0 SAMPLING AND ANALYSIS ACTIVITIES

This section summarizes the sampling activities and presents the analytical

program for the dredge prism and NSM samples obtained at Berths 401 and 410

at Terminal 4. Our activities also included collecting a reference sample in the

Willamette River for contingency biological testing.

3.1 Sediment Core Sampling

On May 8 and 9, 2012, Northwest Underwater Construction (NUC) of

Vancouver, Washington (under subcontract to Hart Crowser), obtained sediment

cores three cores each from Berths 401 and 410 (Figures 2 and 3, respectively).

A representative of Hart Crowser was present to observe and document the

coring activities and to collect dredge prism and NSM samples for analysis.

Positioning. Horizontal positioning was performed using differential GPS. Prior

to field deployment, the coordinates of the proposed core locations were

uploaded into the GPS unit. The vessel was then positioned and anchored as

close to the proposed locations and the actual field coordinates where recorded

at the time of coring. Actual positions were within approximately 10 feet of

planned positions. While positioned over the sample location, vertical

measurements to the sediment surface (i.e., mudline) were made using a

weighted tape (lead line). These depth-to-mudline measurements were used to

calculate a mudline CRD elevation by referencing a United States Geological

Survey (USGS) river gauging station on the Willamette River (Morrison Bridge

Station 14211720). The mudline elevations were generally within 0.5 feet of

those estimated from the July 2011 bathymetry except at core location 401B

which was 1.5 feet different. Table 1 presents the core coordinates and

mudline elevations.

Field Coring Procedures. Cores were obtained using a vibracorer with a 4-inch-

diameter core barrel deployed from a sampling vessel operated by NUC. Cores

were advanced from 9 to 10 feet at Berth 401 and from 5.6 to 7.3 feet at Berth


410, penetrating through the proposed dredge prism and into the underlying

NSM that will remain after dredging. Sediment was contained in a

polycarbonate liner inside of the core barrel.

Upon retrieval of the vibracorer, the liner with core was removed from the core

barrel, the overlying water was drained, and the ends sealed with caps. The

sediment core was examined for acceptance. To obtain sufficient sediment for

contingency biological testing, two cores were needed from each core location.

Acceptable cores used for sampling had core recoveries ranged from 70 to 100

percent. The two cores from location 401A (Figure 2) had slightly less than the

preferred minimum recovery of 75 percent, but these cores were used as they

were the best of five attempts retrieved from this location. The lower recoveries

appeared to be due to core compaction, and the dredge prism and NSM are

believed to be well represented.

Table 1 presents the sediment sampling information, including core identification,

penetration, percent recovery, and target sample intervals. The sediment cores

were then transported to our office for processing.

Core Processing for Samples. Per the SAP (Hart Crowser, 2012), each core

location represents a separate dredged material management unit (DMMU); as

such, one dredge prism sample and one NSM sample was collected, as

described below, for each DMMU (i.e., for each core location). In the

processing area, the core were opened by splitting the core liner lengthwise;

sediment was then photographed and described including, as appropriate,

physical description, odor, visual stratification, debris, and biological activity.

Logs of the cores are included in Appendix A. The percent recovery was re-

measured to derive a compaction correction factor to apply for determining the

sample intervals. Sample intervals were also based on the field-determined

mudline elevations (Table 1).

Dredge Prism Samples. After logging, the following procedures were used to

sample dredge prism sediments from the two cores obtained from each core

location. A discrete sample was obtained from one core for sulfide analyses,

generally near the upper third of the Berth 401 cores and toward the bottom of

the Berth 410 cores (sediments for sulfide analyses cannot be mixed). Sediment

representing the entire depth of the dredge prism from the two cores was then

placed into a stainless steel bowl and homogenized with a stainless steel spoon

until both color and texture were uniform. The homogenized contents from the

cores were then sampled. The sulfide and homogenized dredge prism samples

were both labeled with the berth designation, core location, and the suffix DP

for maintenance dredge prism (e.g., 401A/DP).


NSM Samples. The sampling procedure above was also used for the NSM

samples. The NSM sample interval generally consisted of a 2-foot interval (-42 to

-44 feet CRD) below the dredge prism. Due to the mudline being higher than

expected at core location 401B, only 1.5 feet of NSM sediments was penetrated

(Table 1). A discrete sulfide sample was obtained midway in the NSM interval

from one of the two cores, and the NSM intervals of the two cores were then

homogenized and sampled. The sulfide and homogenized NSM sediment

samples were both labeled with the berth designation, core location, and the

suffix NSM (e.g., 401A/NSM).

3.2 Reference Sediment Sampling

On May 9, 2012, we collected reference sediment for contingency biological

testing from Willamette River mile 19.5 near Elk Rock Island. NUC (under

subcontract to Hart Crowser) used a grab sampler to obtain the sample from the

upper 6.5 inches of sediment. Reference sediment was comprised of a slightly

sandy silt. A sulfide sample was first obtained from sediment retrieved by the

grab sampler. The sediment was placed in a stainless steel bowl, homogenized,

and then transferred into sample containers for chemical and possible biological

testing. Table 1 presents reference sample identification (“Reference”),

coordinates, and mudline depth.

3.3 Analytical Program

Samples collected in Section 3.1 and 3.2 were submitted for chemical analysis

under chain of custody to Analytical Resources, Inc. (ARI), of Tukwila, Washington

(under subcontract to Hart Crowser). Sediment samples for contingency

biological testing were archived (refrigerated) at our office pending chemical

analyses results. Based on the results, biological testing was not performed.

3.3.1 Dredge Prism Samples

Dredge prism samples for the each core location (i.e., each representing a

DMMU) were analyzed to assess the chemical quality of dredge prism, evaluate

whether sediments could qualify for in-water placement, and perform an Oregon

Department of Environmental Quality (DEQ) beneficial use determination (BUD)

for upland placement. The samples were analyzed for the physical and chemical

analyses listed below.

Grain size by ASTM D 421/422;

Total solids by EPA Method 160.3;

Total organic carbon (TOC) by Plumb (1981);


Ammonia by EPA Method 350.1M;

Sulfide by EPA Method 376.2;

Total petroleum hydrocarbons (TPH) as diesel and oil by Northwest Method

NWTPH-Dx with a silica gel cleanup;

Total metals (antimony, arsenic, cadmium, chromium, copper, lead, mercury,

nickel, silver, and zinc) by EPA Method 200.8/7471A;

TBT in bulk sediment by Krone, et al. (written 1988; published 1989);

PAHs by EPA Method 8270D-SIM;

Semivolatile organic compounds (SVOCs) by EPA Method 8270D;

Organochlorine pesticides by EPA Method 8081A; and

PCBs by EPA Method 8082.

3.3.2 NSM Samples

To fully characterize the NSM at Berths 401 and 410, NSM samples were

analyzed for the full suite of chemical analyses listed above except TPH and PAHs.

TPH analysis was only conducted on dredge prism samples for the beneficial use

determination. Additionally, PAH analyses by EPA Method 8270-SIM is performed

to best meet upland risk-based criteria. SVOC analyses provided PAH data, with

method detection limits (MDLs) being sufficiently low to meet SEF SLs.

3.3.3 Reference Sample

Due to holding time constraints and the possibility that biological testing might

be performed, we analyzed the reference sample for total solids, ammonia, and

total sulfides.

3.4 Modifications to the SAP

Field activities and the analytical program were conducted in accordance with

the SAP (Hart Crowser, 2012). As explained below, minor modifications were

made to the field and sampling program as necessitated by field conditions.

A ship was present at Berth 401 and will be for at least several more months;

as such, core location 401B as presented in the SAP could not be

performed. This condition was anticipated in the SAP and an alternate core

location (401B-Alt) was proposed. This alternate location was cored and is

called 401B in this report.


The calculated mudline elevation for core location 401B was 1.5 feet higher

than the estimated elevation based on the July 2011 bathymetry. To

accommodate variability in mudline elevations such as this, we typically

drive the vibracore deeper than stated in the SAP. For 401B, the vibracore

was driven 1 foot deeper to the maximum vibracore length of 10 feet. Still,

this left only 1.5 feet of NSM sediment being recovered instead of the 2 feet

stated in the SAP. We believe that this slightly shorter NSM interval,

however, is representative of the NSM.

4.0 SEDIMENT QUALITY

ARI completed analyses on six dredge prism samples and six NSM samples

corresponding to each of the three DMMUs at Berths 401 and 410. Table 2 lists

the physical results for both berths. Chemical results for Berths 401 and 410 are

listed in Tables 3 and 4, respectively, and are compared to SLs to assess the

chemical quality of the dredge prism and NSM sediments. This section presents

the results and provides an evaluation of them.

4.1 Data Quality Review

A QA review of the data is provided in Appendix B. Method detection limits

(MDLs) were reported for all chemical analyses except conventional analyses. The

laboratory analyzed QC samples, including surrogates, method blanks, laboratory

control samples (LCS), matrix spikes (MS), and laboratory, LCS, and MS duplicates.

Upon review, the overall data quality objectives for collection and chemical testing

of sediment samples were met, and the data for this project are acceptable for use

as qualified. Four QA issues of note are as follows:

The MS for antimony was well below control limits in sample 401A/DP.

Based on our chemist’s review of the data, the antimony results for this

sample and the other DP samples from Berth 401 was rejected (R-flag).

Antimony was not detected in these samples, nor is it a COC at this site

based on previous data.

BEHP was detected in all dredge prism and NSM samples; however, it was

also detected in the method blank (19 µg/kg). Where the sample results

were less than five times the method blank concentration, the sample

concentration was qualified as undetected (U-flag).

The results for DDE in samples 401C/NSM and 410B/NSM, and for DDD in

sample 401B/DP differed by more than 40 percent between the two

chromatographic columns (P-flag). The results were also qualified as

estimated (J-flag).


The CCV for DDx associated with the undiluted analysis of sample

410C/NSM was greater than 15 percent. As such, the DDx results on the

diluted sample (all non-detect) were reported in Table 4. MDLs for DDE and

DDT on the diluted sample exceeded SEF SLs. Although not used, the

undiluted sample results were below SEF SLs for both these compounds

(8.2 µg/kg JP for DDE and non-detect at 0.18 µg/kg for DDT).

Several undetected and detected results were also J-flagged as estimated for

reasons explained in Appendix B. Laboratory reports for chemical analysis,

including QC samples, are included in Appendix C.

4.2 Grain Size Characteristics

The grain size results on the dredge prism samples are presented in Table 2, and

grain size distribution curves are provided in Appendix C.

Berth 401. The dredge prism at core locations 401A and 401B consists of silty

sand or sandy silt (43 to 65 percent fines); these sediments overlie sand in the NSM

(less than 13 percent fines). At location 401C, dredge prism and NSM sediments

consist of primarily slightly sandy to sandy, clayey silt (over 83 percent fines).

Berth 410. The dredge prism and NSM samples at core location 410A consisted

of very silty sand (50 to 51 percent fines). Further into the Slip 3 at locations

410B and 410C, the dredge prism and NSM samples were comprised of a silty

sand (22 to 40 percent fines).

4.3 Comparison to SEF Screening Levels

Table 3 presents the chemical results on sediment samples. These results were

compared to the SEF SLs. These SLs were established in the SEF for protection of

the aquatic environment and to provide a uniform framework for evaluating

sediment quality of dredged material for unconfined aquatic disposal. Freshwater

SEF SLs have not been finalized, so SLs in Tables 3 and 4 are freshwater Screening

Level 1 values from Table 7-1 of the Interim Final SEF (Corps, et al., 2006; table

revised October 20, 2006). Pesticides compounds do not have SL1 values so the

Corps indicates marine SEF SLs are to be used (Corps, et al. 2009, Table 6-3).

4.3.1 Berth 401

Analytical results for the dredge prism and NSM samples were compared to SEF

SLs in Table 3. As indicated below, only two chemicals (TBT and zinc) exceeded

SEF SLs in the dredge prism. NSM samples were below SEF SLs.


Dredge Prism Samples. Analytical results on the dredge prism samples only

detected two chemical compounds above SEF SLs: TBT at 140 µg/kg (SL of 75

µg/kg) in core location 401A downstream of Berth 401, and zinc at 132 mg/kg

(SL of 130 mg/kg) at location 401B, in the upstream mid-section of the berthing

area. Other metals, TPH as diesel and oil, PAHs, several SVOCs, DDD, DDE,

and PCBs were also detected, but below SEF SLs.

NSM Samples. Chemical analysis of sample 401B/NSM only detected

background concentrations of several metals. Results on the other two NSM

samples detected metals, TBT, PAHs, several SVOCs, DDD, DDE, and PCBs;

however, all detections were below SEF SLs.

4.3.2 Berth 410

Results for the dredge prism and NSM samples were compared to SEF SLs in

Table 5. Chemical results show several SEF exceedances (zinc, PAHs, and/or

PCBs) in dredge prism and NSM sediments at core location 410C in the eastern

portion of the Berth 410. There was a slight exceedance of one PAH in the

NSM at location 410B in the middle of the berth.

Dredge Prism Samples. Analytical results on dredge prism samples indicated

that the only SEF SL exceedances were four chemical compounds in sample

410C/DP from the eastern portion of the Berth 410. Benzofluoranthenes were

above their SEF SL (exceedance ratio of 10); however, zinc, benzo(a)pyrene, and

HPAHs were only slightly above their respective SLs (exceedance ratios less than

1.2). Other metals and PAHs, TPH as diesel and oil, TBT, several SVOCs, DDD,

DDE, and PCBs were also detected in this sample and the other two dredge

samples; however, these detections were below SEF SLs.

NSM Samples. Chemical results did not indicate any SEF SL exceedances for

sample 410A/NSM. Only benzofluoranthenes exceeded their SEF SL in sample

410B/NSM (640 µg/kg; SL of 600 µg/kg). In sample 410C/NSM, cadmium, zinc,

and benzofluoranthenes had exceedance ratios of near or less than 2, and total

PCBs were present at an estimated concentration of 435 µg/kg (exceedance ratio

of 7.3). Lead (201 mg/kg) and sulfide (150 mg/kg) were relatively high, but did

not exceed SLs. Other metals, TBT, several SVOCs, DDD, and DDE were also

detected NSM samples, but below SEF SLs.

4.4 Data Evaluation

Sediment characterization results indicated that several chemical compounds at

each berth exceeded SEF SLs. As such, the data for each berth were evaluated


for possible placement options for dredge prism sediments and potential aquatic

effects from exposure of the NSM after dredging.

4.4.1 Berth 401

Sediment data from the downstream DMMU, represented by core 401A,

indicates that the dredge prism is not suitable for in-water placement due to the

presence of TBT above its SL (140 µg/kg versus SL of 75 µg/kg). Overall,

chemical concentrations in the DMMU are relatively low and upland placement

under a DEQ-approved BUD is likely. Exposure of the NSM at this downstream

end would not pose any effects to the aquatic environment (results below SLs;

similar to dredge prism sediments).

For the mid-berth DMMU, only zinc in 401B was barely above its SL in dredge

prism (exceedance ratio of 1.02). Previous investigations, however, found TBT in

the mid-berth area. This area could not be sampled because of a ship in lay

berth. In 2006, TBT was detected 1,000 µg/kg in a composite sample of NSM

sediments (Anchor, 2006). A subsequent TBT-characterization study determined

that TBT was present above its SEF in the mid-berth area to a depth of -44 feet

CRD (a sample from -43 to -44 feet CRD had 230 µg/kg TBT; the next deeper

sample was non-detect for TBT [Anchor, 2007; Hart Crowser, 2012). Dredging

shallower than -44 feet CRD may leave TBT above SEF SLs in the NSM. As such,

we recommend that dredging to -44 feet CRD be conducted mid-berth. While

TBT and zinc preclude in-water placement of dredged material, the material is

likely suitable for upland placement under a BUD.

The upstream DMMU met SEF SLs so dredged material is suitable for both in-

water and upland placement. Exposure of the NSM at the upstream end would

not pose any effects to the aquatic environment (results below SLs; similar to

dredge prism sediments).

4.4.2 Berth 410

Sediment data from the west and mid-berth DMMUs, represented by cores 410A

and 410B, indicates that the dredge prism is suitable for both in-water and upland

placement. Exposure of the NSM is not anticipated to not pose an adverse effect

to the aquatic environment, as results below SEF SLs with the exception of

benzofluoranthenes. Benzofluoranthenes were detected in sample 410B/NSM at

640 µg/kg, slightly above the SEF SL of 600 µg/kg (exceedance ratio of 1.07).

This result is within the laboratory error: the relative percent difference (RPD) of

6.5 percent between the result and the SL is similar to the RPD of the associated

laboratory control sample and its duplicate (6.6 percent). As such, we believe

that this minor exceedance does not pose an aquatic concern.


Chemical results from the eastern DMMU of Berth 410 (core location 410C)

indicate that the dredge prism sediment is not suitable for in-water placement

and, due to high PAH concentrations, may not be approved by the DEQ for

upland placement. NSM sediments are lower in PAH concentrations, but have

relatively higher lead, zinc, and PCB concentrations. Cadmium, zinc,

benzofluoranthenes, and PCBs exceeded SEF SLs in the NSM, but only PCBs

were much higher than its SL. As such, exposure of the NSM in the eastern

portion of Berth 410 may pose a possible aquatic concern.

5.0 SUMMARY

The Port is proposing to conduct maintenance dredging at Berths 401 and 410

to maintain the navigational depth clearances for vessels docking at these berths.

In May 2012, we obtained three sediment cores from each berth. Sediment

from each core was sampled to represent the dredge prism and future NSM.

Samples were submitted for physical and chemical analyses.

Chemical results from cores completed at Berth 401 indicate that dredge prism

sediment from the downstream and mid-berth DMMUs is not suitable for in-

water placement, but upland placement under a BUD is likely. Due to previous

detections of TBT in the mid-berth area, we recommend dredging to -44 feet

CRD in this area. Sediments from the upstream DMMU are suitable for both

in-water and upland placement. After dredging, exposure of the NSM does not

pose a concern to the aquatic environment.

Data from Berth 410 indicate that western and mid-berth DMMU sediments are

suitable for both in-water and upland placement. Exposure of the NSM is

unlikely to have an adverse impact on the aquatic environment. The eastern

DMMU has relatively high concentrations of PAHs, which would likely preclude

in-water or upland placement; as such, this dredged material would require

landfill disposal. The NSM in this area also has SEF SL exceedances, and

additional post-dredge assessment or actions may be necessary to assess for or

mitigate, respectively, impacts to the aquatic environment.

Notes:

1. Screening levels (SLs) are Freshwater Screening Levels 1 (no adverse effects) from the Sediment Evaluation

Framework (SEF) (Corps, et al., 2006; Table 7-1, revised 10/20/06). For pesticides, no freshwater SLs have been

established and the Corp uses marine SLs from corrected Table 6-3 of the Final SEF (Corps, et al., 2009). These

marine SLs are listed and flagged with an a.

2. PAH and dibenzofuran concentrations are the higher of the lowest acceptable dilution of the EPA Method 8270D-SIM and

EPA Method 8270D analyses.

3. Bolded values are detected concentrations.

4. For undetected compounds, method detections limits (MDLs) are shown.

5. - = Not analyzed or not available.

6. J = Estimated concentration. Result may be estimated due to value between MDL and method reporting limit (MRL),

or due to QA exceedance.

7. U = Not detected at the indicated MDL.

8. P = The analyte was detected on both chromatographic columns but the RPD was greater than 40%.

9. Reference sample results: 51.7% solids, 29.9 mg/kg ammonia, and 2.51 mg/kg total sulfides.

APPENDIX B QUALITY ASSURANCE REVIEW

Hart Crowser Page B-1 15753-00 July 11, 2012

APPENDIX B

QUALITY ASSURANCE REVIEW

This appendix documents the results of a quality assurance (QA) review of

the analytical data for dredge prism and new surface material (NSM) samples

collected during the May 2012 sediment characterization at the Berths 401 and

410. Field procedures used for sample collection are discussed in our Sampling

and Analysis Plan (SAP; Hart Crowser, 2011). Hart Crowser submitted sediment

samples to Analytical Resources, Inc. (ARI), of Tukwila, Washington, for chemical

analysis. A copy of the analytical laboratory report (ARI Job No. UU16) is

included in Appendix C. Upon review, the analytical data are valid with minor

qualifications for their intended use. A Data Completeness (QA1) checklist is

included as Table B-1 in this appendix.

The quality assurance review included examination and validation of the

laboratory’s summary reports, including:

Holding times;

Method blanks;

Surrogate recoveries;

Laboratory control sample/laboratory control sample duplicate

(LCS/LCSD) recoveries;

Standard reference material (SRM) recoveries;

Matrix spike and matrix spike duplicate (MS/MSD) recoveries;

Calibration criteria;

Internal Standard (IS) recoveries, where applicable;

Laboratory duplicate relative percent difference (RPD), where applicable; and

Laboratory replicate relative standard deviation (RSD), where applicable.

A Level IV Data Deliverables Package was available for review.

ANALYTICAL METHODS AND DETECTION LIMITS

Chemical Analyses on Sediment

Six cores were obtained during the sediment characterization fieldwork on

May 8 and 9, 2012, with three cores from Berth 401 and three cores from


Berth 410. Each core was divided into two sections to represent the dredge

prism and the NSM interval, for a total of twelve sediment samples. A reference

sample was collected on May 9, 2012, and submitted with the core samples.

The sediment samples were analyzed for one or more of the following:

Total solids by EPA Method 160.3 modified;

Total organic carbon (TOC) by Plumb (1981);

Ammonia by EPA Method 350.1 modified;

Sulfide by EPA Method 376.2;

Total metals (antimony, arsenic, cadmium, chromium, copper, lead, mercury,

nickel, silver, and zinc) by EPA Methods 200.8/7471A;

Total petroleum hydrocarbons as diesel and oil by Northwest Method

NWTPH-Dx with silica gel and acid cleanup;

Tributyltin (TBT) by Krone, et al. (written 1988; published 1989);

Polycyclic aromatic hydrocarbon (PAHs) by EPA Method 8270D-SIM;

Semivolatile organic compounds (SVOCs) by EPA Method 8270D;

Organochlorine pesticides by EPA Method 8081A;

Polychlorinated biphenyls (PCBs) by EPA Method 8082; and

Grain size by ASTM D421/D422.

These analytical test methods were the analytical methods specified in the

SAP (Hart Crowser, 2012) or in the case of metals (except mercury) is an

equivalent method.

Detection and Reporting Limits

Method detection limits (MDLs) are the minimum concentration of a chemical

compound that can be measured and reported that the compound is present,

and is based on instrumentation abilities and sample matrix. Method reporting

limits (MRLs) are set by the laboratory and are based on the low standard of the

initial calibration curve or low-level calibration check standard, and represent the

concentration that can be accurately quantified. In some cases, the MRL is

raised due to high concentrations of analytes in the samples or matrix

interferences. MRLs were consistent with industry standards. Tables 3 and 4 of

this report list the MDLs for undetected values. The MDLs are sufficient in

achieving the SEF SLs listed in Tables 3 and 4. Analytical results that fell between

the MDL and MRL are qualified as estimated (J).


QA REVIEW RESULTS

The laboratory provided QC sample results, which were underwent a QA

review. Laboratory QC samples were consistent with those specified in the SAP

(Hart Crowser, 2012) to evaluate precision, accuracy, representativeness,

comparability, and completeness. Upon review, the sample data and laboratory

QC data were found to be suitable for their intended use with minor

qualifications. The following summarizes, by analyte or test, the results of our

QA review of the analytical data.

Total Solids. All required holding times were met. No method blank

contamination was detected. The laboratory replicate RSD was acceptable.

TOC. All required holding times were met. No method blank contamination was

detected. LCS, MS, and SRM recoveries were within control limits. The laboratory

replicate RSD was acceptable.

Ammonia. All required holding times were met. No method blank contamination

was detected. SRM and MS recoveries were within control limits. The laboratory

replicate RSD was acceptable.

Sulfide. All required holding times were met. No method blank contamination

was detected. The LCS and MS recovery were within laboratory control limits.

The laboratory duplicate RPD was within 30 percent.

Total Metals. All required holding times were met. No method blank

contamination was detected. LCS recoveries were within control limits for all

elements. The laboratory duplicate RPD was acceptable. MS recoveries were

within control limits except for antimony in sample 401A/DP. In this case,

antimony (0%) was below control limits. A post digestion spike for antimony

was analyzed and fell within control limits. Results for antimony were rejected

(R) in the source sample (401A/DP) and two matrix-similar associated samples

(401B/DP and 401C/DP). Non-detected results for antimony in the remaining

samples were qualified as estimated (UJ).

TPH as Diesel and Oil. All required holding times were met. No method blank

contamination was detected. Surrogate and LCS recoveries were within

laboratory control limits. The initial calibration curve and continuing calibrations

were within acceptance criteria.

Tributyltin. All required holding times were met. No method blank

contamination was detected. Surrogate, LCS, and MS recoveries were within


laboratory control limits. IS recoveries were within acceptance criteria. The initial

calibration curve and continuing calibrations were within acceptance criteria.

PAHs. All required holding times were met. No method blank contamination

was detected. Surrogate and LCS recoveries were within laboratory control

limits. IS recoveries were within acceptance criteria.

MS recoveries were within control limits except for the recovery for phenanthrene

in sample 410B/DP was below the marginal exceedance (ME) limits in the MS and

MSD. The recoveries for fluoranthene and pyrene fell below the control limits, but

were within the ME limits in the MSD; these compounds were within the control

limits in the MS. Results for phenanthrene in the source sample (410B/DP) were

qualified as estimated (J). Results for fluoranthene and pyrene were not qualified

as the MS was within control limits.

The initial calibration curve was within acceptance criteria. CCVs were within

control limits except for the recovery for benz(a)anthracene on May 14, 2012,

was low. The laboratory qualified detections in the associated samples with Q.

The Q qualifier was changed to J (estimated) in the associated samples

(401A/DP, 401B/DP, 401C/DP, 410A/DP, 410B/DP, and 410C/DP).

SVOCs. All required holding times were met. Surrogate and LCS recoveries

were within laboratory control limits. IS recoveries were within acceptance

criteria. The initial calibration curve was within acceptance criteria.

The method blank was non-detect except for bis(2-ethylhexyl)phthalate (BEHP)

was detected between the MDL and the RL at 19 µg/kg. The laboratory

qualified detections in the associated samples with “B”. The results were

evaluated as follows.

Sample results that were greater than five times the method blank detection

had the B qualifier removed (401C/DP and 410C/NSM).

Sample results for BEHP that were less than five times the method blank

detection were qualified as U (all other samples).

MS recoveries were within control limits except for the recovery for benzoic

acid in sample 410B/NSM failed low in the MSD, but passed in the MS.

Associated sample results were not qualified, as the recovery passed in the MS.

The RPD for dibenz(a,h)anthracene exceeded the control limits. As the

recoveries for dibenz(a,h)anthracene were in control in the MS and MSD,

sample results were not qualified.


CCVs were within control limits with the following exceptions:

CCV 05/12/12: The recovery for pentachlorophenol (PCP) failed low. The

results for PCP in the associated samples (401A/DP, 401B/DP, 401C/DP,

401A/NSM, 401B/NSM, 401C/NSM, 410A/DP, 410B/DP, 410C/DP,

410A/NSM, 410B/NSM, and 410C/NSM) were non-detect and qualified as

estimated (J).

CCV 05/14/12: The recoveries for PCP and benzoic acid failed low. The

associated sample, 410C/DP, was a diluted reanalysis, and results for PCP

and benzoic acid were reported from the undiluted analysis. No sample

results were qualified.

For samples 410A/DP, 410A/NSM, 410C/NSM, and 410C/DP, phenol results

were qualified by the laboratory with M due to low spectral match parameters.

The sample results are estimated, and the M qualifier was changed to J.

Organochlorine Pesticides. All required holding times were met. No method

blank contamination was detected. LCS recoveries were within control limits. IS

recoveries were within acceptance criteria. The initial calibration curve was

within acceptance criteria.

Surrogate recoveries were within laboratory control limits except for the dilution

for sample 410C/NSM. The sample was analyzed at a 100-fold dilution, and the

surrogates were not recovered. Surrogate recoveries were within control in the

undiluted analysis, and no sample results were qualified.

MS recoveries were within laboratory control limits except for sample

410B/NSM. The recoveries for 4,4’-DDT failed low in the MS and MSD. The

results were reported from an analysis with a failing DDT breakdown check, and

therefore, these results for 4,4’-DDT, 4,4’-DDD, and 4,4’-DDE are not valid.

Associated sample results were not qualified due to the MS and MSD failures.

CCVs were within control limits with the following exceptions:

CCVs 05/15/12 at 0723, 1133, 1636, 2138 and 05/16/12 at 0539: The

recoveries for delta-BHC failed high on the STX-CLP2 column, but passed on

the STX-CLP1 column. The analyte delta-BHC was not a target analyte, and

no results were qualified.

DDT Breakdown Check 05/16/12 at 1006: The breakdown check exceeded

15 percent on both columns. Results for 4,4’-DDT, 4,4’-DDD, and 4,4’-DDE

in the associated sample 410C/NSM were reported from the diluted analysis

on 05/15/12 with elevated reporting limits. Results for 4,4’-DDT, 4,4’-DDD,


and 4,4’-DDE in the associated MS and MSD were not valid. The MS and

MSD were also analyzed at dilution on 05/15/12.

CCV 05/16/12 at 1024: The recoveries for 4,4’-DDE, 4,4’-DDD, and gamma-

chlordane failed high on the STX-CLP1 column, while the recoveries for

4,4’-DDT and methoxychlor failed low. The recoveries for delta-BHC and

4,4’-DDD failed high on the STX-CLP2 column, while the recoveries for

4,4’-DDT and methoxychlor failed low. The analytes delta-BHC,

methoxychlor, and gamma-chlordane were not target analytes, and no results

were qualified. As the associated DDT breakdown check failed, no results for

4,4’-DDT, 4,4’-DDD, and 4,4’-DDE were reported from this analysis.

DDT and Endrin Closing Breakdown Checks 05/16/12 at 1229: The DDT

breakdown check exceeded 15 percent on both columns; the Endrin

breakdown check exceeded 15 percent on the STX-CLP2 column. Endrin was

not a target analyte, and sample results were not affected. The laboratory

used the internal standard method for analysis, and the closing CCVs and

breakdown checks do not affect the preceding sample analysis. No samples

were qualified.

The results for 4,4’-DDE in samples 401C/NSM, 410C/NSM, and 410B/NSM

and for 4,4’-DDD in sample 410B/DP differed by more than 40 percent between

the two chromatographic columns. The laboratory qualified the results with “P”.

The P qualifier was changed to JP.

The reporting limits for trans-chlordane in sample 410C/DP were elevated by the

laboratory due to chromatographic interferences and qualified with “Y”. The Y

qualifier was changed to U. The reporting limits for 4,4’-DDT in sample

410C/NSM were elevated by the laboratory due to chromatographic

interferences and qualified with “Y”. Sample results were reported from the

diluted analysis due to CCV failures.

PCBs. All required holding times were met. No method blank contamination

was detected. Surrogate and LCS recoveries were within laboratory control

limits. IS recoveries were within acceptance criteria. The initial calibration curve

and continuing calibrations were within acceptance criteria. The reporting limits

for Aroclors 1248 and 1262 in sample C 1/2-DP were elevated by the laboratory

due to chromatographic interferences and qualified with “Y”. The reporting

limits for Aroclor 1232 in sample C3/4-N2 were elevated by the laboratory due

to chromatographic interferences and qualified with “Y”. Y qualifiers on sample

results were changed to U.

PCBs. All required holding times were met. No method blank contamination

was detected. LCS and MS recoveries were within laboratory control limits. IS


recoveries were within acceptance criteria. The initial calibration curve and

continuing calibrations were within acceptance criteria. Surrogate recoveries

were within laboratory control limits except for sample 410C/NSM. In this case,

the recoveries for the surrogates TCMX and DBCP exceeded the control limits.

The associated sample results were qualified as estimated (J).

The reporting limits for Aroclors 1242 in sample 410B/DP were elevated by the

laboratory due to chromatographic interferences. The reporting limits for Aroclor

1254 in samples 401A/DP and 401A/NSM were elevated by the laboratory due to

chromatographic interferences. The reporting limits for Aroclors 1248 and 1254

were elevated by the laboratory in samples 401A/DP, 401B/DP, 401C/DP,

401C/NSM, 410C/NSM, 410A/NSM, and 410B/NSM due to chromatographic

interferences. The reporting limits for Aroclors 1242 and 1254 were elevated by

the laboratory in samples 410A/DP due to chromatographic interferences. The

laboratory qualified the affected results with “Y”. The Y qualifier was changed to U.

The results for Aroclor 1248 in samples 401A/DP and 410C/NSM differed by more

than 40 percent between the two chromatographic columns. The laboratory

qualified the results with “P”. The P qualifier was changed to JP.

Grain Size. All required holding times were met. The laboratory triplicate RSD

was within criteria.
